Abstract

Champaran district of north Bihar bestows a wide range of wetlands together with intricate net of rivers. These all and its geographical location has given unique climatic condition to this district. Phytoplankton and zooplankton relationship in four freshwater bodies of the area, viz., Turkaulia lake, Motijheel lake, Kararia lake and Suraha lake has been studied. Rotifers were dominating over the other zooplankton. It was observed that zooplankton and phytoplankton are somehow related. In addition, some physical and chemical factors may also play an important role in maintaining such relationship, which may influence their growth.

Keywords

Phytoplankton, Zooplankton, Population Density, Lentic Water Bodies.

Abstract

Observations on the gut contents of six species of edible fishes of Motijheel, Motihari were made at different intervals from January 2005 to December 2006. The results show that fishes feed on a particular type of food available in different zones of the water body. On the basis of food nature, the studied fishes may be grouped as herbivorous, carnivorous and omnivorous. Similarly, on the basis of feeding habits some fishes are found to be surface feeder, some mid feeder, and others as bottom feeder. In the present study special emphasis has been given on the nature of food contents examined in the gut of the studied fishes.

Keywords

Edible Fishes, Feeding Habits, Gut Contents, Motijheel Lake.

Abstract

Birganj is a sub-metropolitan town and headquarters of Parsa district (Nepal) situated at about 6 km distance towards north of Raxaul, the Indian border. There is an important water body situated in heart of the town, known as Ghariyarwa pond. An ecological study of this famous pond was made with respect to its physico-chemical characteristics and growth of planktonic algae. Physico-chemical analysis of the pond water exhibited good amount of alkalinity, chloride and phosphate which favour growth of phytoplankton. Chlorophyceae and Cyanophyceae were observed maximum during rainy season, while Bacillariophyceae during winter.

Abstract

Haematological studies of Cyprinus carpio in the present work include the erythrocyte count, haemoglobin concentration and haematocrit value or packed cell volume of blood, and subsequently absolute values of M.C.V., M.C.H. and MCHC were calculated by the respective formulae. The major effects of nickel on the blood parameters are concerned with total count of RBC, their size and differential count of WBC. The significance of the present study is concerned with metallic pollution of major rivers of Jharkhand state.
